COLLAISIBLE TUBE.

Specification of Letters Patent.

Patented May 22, 1917.

Application filed August 16, 1916. Serial No. 115,291.

To all whom it may concern:

Be it known that I, FREDERICK /VILLIAM GRIES, a citizen of the United States, residing at lVatervliet, in the county of Albany and State of New York, have invented new and useful Improvements in Collapsible Tubes, of which the following is a specification.

This invention relates to improvements in tubes and more particularly to a collapsible tube adapted to contain' tooth paste, shaving paste, glue, library paste, photographic paste, cold cream, other similar substance sold and used in tubes of the collapsible type.

The primary object of the invention is the production of a tube of the above stated character wherein the outlet opening thereof is formed lengthwise of the neck, whereby the contents of the tube when discharged through such opening is formed with grooves, thus preventing any accidental slipping of the tooth paste from the tooth brush previous to applying the paste to the teeth.

A still further object of the invention resides in forming a guide post with the neck of the tube for slidably supporting the cap of the tube thereon and preventingany accidental loss or displacement of the cap from the container.

With the above and other objects in View, the invention consists in the novel features, details of construction and combination of parts which will hereinafter be more fully set forth, illustrated in the accompanying drawings claims.

Figure 1 is a perspective view of a device constructed in accordance with my invention, and illustrating the tube in closed position;

Fig. 2 is a similar view to Fig. 1, showing the cap in an elevated or open position;

Fig. 3 is a plan view of a tooth brush showing the tooth paste applied thereto;

Fig. 4 is a view similar to Fig. 2, showing the cap removed from the post;

Fig. 5 is a detail sectional view of the cap showing the .cork disk disposed therein; and

-Fig.' 6 is a view similar to Fig. 4, showing a quantity of liquid paste passing out of the outlet opening.

Referring more particularly to the accompanying drawings, in which like charpetroleum jellies, andand pointed out in the appended" acters .of reference refer to corresponding parts in the several views, 5 denotes the body portion of the collapsible tube adapted to contain therein a tooth cleansing preparation, preferably of paste form, but I desire to have it understood that this tube is adaptable to hold shaving paste, glue, library paste, photographic paste, cold cream, petroleum jellies, and other like substances sold and used in collapsible tubes of the collapsible type. This tube is constructed of the well-known type of material and is provided at its upper end with a depressed annular portion 6 in which is inserted a cork 7, the purpose of which will be hereinaftei more fully set forth. Rising centrally from the depressed annular portion 6 of the tube is an externally threaded hollow tubular neck 8 having formed on the top thereof a perpendicular an enlarged flattened terminal 10 for preventing any accidental displacement of the cap 11 therefrom upon the unscrewing of the cap from the neck 8 of the tube. This cap is formed with an internally threaded bore 12 for threadedly engaging with the threads 13 of the neck, and when'the said cap is in a lowered or closed position, the lower open end thereof, designated by the character 14, will fit down in the depressed annular portion 6 ofthe tube and repose upon the cork insert 7, thus establishing a liquid tight connection of the cap with the tube, the purpose of which will be apparent to those skilled in the art to which the'invention relates. Mounted internally of the cap 11 and in abutting engagement with the closed upper end 15 thereof is a cork disk 16 which is brought to bear against the upper end 17 of the neck when the former is in closed position, preventing the accumulation of moisture or the entering of air within the tube. Formed in one side of the neck is a vertically disposed narrow curved discharge slot 18,. formed in the neck by mutilating certain of the threads 13 thereo and by so doing provides the opposite side walls 19 of the slot with a serrated face 20. The forming-of the serrations in the side walls 19 of the slot provides grooves in the tooth cleansing paste, as the same is ejected through the slot 18 of the neck, which in turn prevents the cleansing paste 21 from accidentally skidding or slipping from the brush head 22 during the cleansing operation of the teeth. Furthermore, in view of guide post 9 terminating in the fact that the slot is of a narrow or elongated form will serve to discharge the cleansing paste in strip or layer form of an approximate width equaling the transverse dimensions of the bristles 22 and enabling an even flow of the cream or paste from i the body portion of the container.

The enlarged upper fiat end of the guide post 9 is utilized as a stop. for the cap, whereby upon the engagement of the closed upper end therewith will indicate to the user or operator of the tube that the cap has been sufficiently unscrewed to open the slot 18 in the neck, and as previously stated, this stop v1O further serves as a means for preventing any accidental displacement or loss of the cap from the neck. By so doing, the cream or paste is retained in'a soft state at all times.

From the foregoing description, taken in connection with the accompanying drawing, the advantages of construction and of the method of operation will be readily apparent to those skilled in the art to which the invention relates, and while I have described the principles of operation of the invention, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made when desired as are within the scope of the claims appended thereto.

I claim:

1. A device of the class described embodying a cylindrical hollow body portion provided with an exteriorly threaded neck formed with an outletslot, a perpendicular member formed contiguous with the upper end of the neck, a member threadedly mounted upon the neck and slidably mounted upon the perpendicular member for closing said cap.

2. A device of the class described embodying a hollow cylindrical body portion provided at its upper end with an annular counter-sunk portion, a layer of cork in serted in the counter-sunk portion of the tube, an exteriorly threaded neck rising centrally from said counter-sunk portion, a cap threadedly mounted on said neck, said cap when in closed position adapted to bear against said layer of cork and establishing a liquid tight connection between the cap and tube.

3. A device of the class described embodying a hollow cylindrical body portion provided at its upper end with an annular counter-sunk portion, a layer of cork insertedin the counter-sunk portion of the tube, an eXteriorly threaded neck rising centrally from said counter-sunk portion, a cap threadedly mounted on said neck, said cap when in closed position adapted to bear against said layer of cork and establishing a liquid tight connection between said cap and tube, and means rising from the cap for preventing any accidental displacement of the latter from said neck.

4. A device of the class described embodying a hollow cylindrical body portion provided at its upper end with an annular counter-sunk portion, a layer of cork inserted in the counter-sunk portion of the tube, an exterior-1y threaded neck rising centrally from said counter-sunk portion,-

a cap threadedly mounted on said neck, said cap when in closed position adapted to bear against said layer of cork and establishing a liquid tight connection between said cap and tube, and a guide post rising from the neck and having an enlarged upper end, the enlarged upper end of said post preventing any acci ental displacement of the cap from the container upon the raising of the former to an open position.

In testimony whereof I afiiX my signature.

FREDERICK WILLIAM GRIES.
